<h2>Parts and Styles<a class="headerlink" href="#parts-and-styles" title="Permalink to this headline">¶</a></h2>
<p>The Gauge's main part is called <code class="docutils literal notranslate"><span class="pre">LV_GAUGE_PART_MAIN</span></code>. It draws a background using the typical background style properties and &quot;minor&quot; scale lines using the <em>line</em> and <em>scale</em> style properties.
It also uses the <em>text</em> properties to set the style of the scale labels. <em>pad_inner</em> is used to set space between the scale lines and the scale labels.</p>
<p><code class="docutils literal notranslate"><span class="pre">LV_GAUGE_PART_MAJOR</span></code> is a virtual part which describes the  major scale lines (where labels are added) using the <em>line</em> and <em>scale</em> style properties.</p>
<p><code class="docutils literal notranslate"><span class="pre">LV_GAUGE_PART_NEEDLE</span></code> is also virtual part and it describes the needle(s) via the <em>line</em> style properties.
The <em>size</em> and the typical background properties are used to describe a rectangle (or circle) in the pivot point of the needle(s).
<em>pad_inner</em> is used to to make the needle(s) smaller than the outer radius of the scale lines.</p>

<h3>Set value and needles<a class="headerlink" href="#set-value-and-needles" title="Permalink to this headline">¶</a></h3>
<p>The gauge can show more than one needle.
Use the <code class="docutils literal notranslate"><span class="pre">lv_gauge_set_needle_count(gauge,</span> <span class="pre">needle_num,</span> <span class="pre">color_array)</span></code> function to set the number of needles and an array with colors for each needle.
The array must be static or global variable because only its pointer is stored.</p>
<p>You can use <code class="docutils literal notranslate"><span class="pre">lv_gauge_set_value(gauge,</span> <span class="pre">needle_id,</span> <span class="pre">value)</span></code> to set the value of a needle.</p>
</div>

The default settings are 220 degrees, 6 scale labels, and 21 lines.</p>
<p>The scale of the Gauge can have offset. It can be adjusted with <code class="docutils literal notranslate"><span class="pre">lv_gauge_set_angle_offset(gauge,</span> <span class="pre">angle)</span></code>.</p>
</div>
<div class="section" id="range">
<h3>Range<a class="headerlink" href="#range" title="Permalink to this headline">¶</a></h3>
<p>The range of the gauge can be specified by <code class="docutils literal notranslate"><span class="pre">lv_gauge_set_range(gauge,</span> <span class="pre">min,</span> <span class="pre">max)</span></code>. The default range is 0..100.</p>

<div class="section" id="needle-image">
<h3>Needle image<a class="headerlink" href="#needle-image" title="Permalink to this headline">¶</a></h3>
<p>An images also can be used as needles. The image should point to the right (like <code class="docutils literal notranslate"><span class="pre">==&gt;</span></code>). To set an image use <code class="docutils literal notranslate"><span class="pre">lv_gauge_set_needle_img(gauge1,</span> <span class="pre">&amp;img,</span> <span class="pre">pivot_x,</span> <span class="pre">pivot_y)</span></code>. <code class="docutils literal notranslate"><span class="pre">pivot_x</span></code> and <code class="docutils literal notranslate"><span class="pre">pivot_y</span></code> are offset of the rotation center from the top left corner. Images will be recolored to the needle's color with <code class="docutils literal notranslate"><span class="pre">image_recolor_opa</span></code> intensity coming from the styles in <code class="docutils literal notranslate"><span class="pre">LV_GAUGE_PART_NEEDLE</span></code>.</p>

<div class="section" id="critical-value">
<h3>Critical value<a class="headerlink" href="#critical-value" title="Permalink to this headline">¶</a></h3>
<p>To set a critical value, use <code class="docutils literal notranslate"><span class="pre">lv_gauge_set_critical_value(gauge,</span> <span class="pre">value)</span></code>. The scale color will be changed to <em>scale_end_color</em> after this value. The default critical value is 80.</p>
